What Only a Select Group of Psychologists Know About Moral Injury

Moral injury promises a new way to understand suffering—but delivers no clear diagnosis, no unique treatment, and no empirical boundaries.

This Happened
Over the past decade and a half, a new construct has steadily gained traction in trauma research: moral injury. The first paper using the term appeared in 2009. Since then, more than a thousand papers have been published invoking it. By volume alone, one might assume a robust and well-established scientific construct. The reality is less reassuring.
Who Did This?
The leading figure in this literature is psychologist Brett Litz, based at the Veterans Administration Boston Healthcare System. Litz authored the original 2009 paper and has since contributed over three dozen more as primary or secondary author.
The Claim
Moral injury can be an event or an outcome. “Potentially morally injurious events” (PMIEs) are acts that violate a person’s moral beliefs—whether through commission, omission, or witnessing. While moral distress is assumed to be a normal response, moral injury is said to occur when distress crosses a threshold into impairment.
Analysis
At first glance, this sounds plausible. But the following uncomfortable facts are undisputed even by proponents of moral injury:

• There is no gold-standard assessment.
• There is no consensus definition of a moral injury syndrome.
• There is no convincing evidence that moral injury is distinct from PTSD, and most researchers describe it as a subset of PTSD rather than a separate condition.
• Advocates also claim that moral injury can arise from events that do not involve life threat—unlike PTSD—yet there is not a single well-documented case study demonstrating this.
• There is no evidence that any treatment uniquely reduces “moral injury” symptoms as such, including therapies designed specifically for that purpose. Most PTSD experts conclude that standard evidence-based PTSD treatments are sufficient [2].

 
Additional problems are barely or never mentioned:

• Over a dozen self-report questionnaires exist, but there is no interview-based measure.
• The questionnaires fail to specify qualifying events, meaning virtually any subjectively upsetting experience can count.
• Morality itself is not a unitary construct. Social psychologists identified at least six distinct moral domains, yet the moral injury literature has shown zero interest in determining which morals are supposedly “injured,” or how. The “morals” in moral injury are almost completely unexplored.
• Of most concern, individuals identified as “morally injured” most likely have pre-existing traits such as anxiety or neuroticism and histories of distress to many non-moral situations, yet no researcher has ever looked for this to my knowledge. Translation: moral injury might never be a unique type of worry.

Why Is This Happening?
Given this thin empirical footing, the obvious question is: why does moral injury have any momentum? Well, we’ve seen this all before. 

Trauma research has a long history of seductive ideas outrunning evidence. Moral injury appears to be following the script.

​The trauma field has repeatedly produced concepts—complex PTSD, toxic stress, trauma-informed care—that marinated weak evidence in the academies for years before suddenly exploding with “consensus-based” clarity into institutional acceptance, training programs, and policy relevance. 

Moral injury has now been marinating for about sixteen years. It may be next in line: Emotionally powerful but scientifically underdeveloped, ready to be deployed in therapy markets, workshops, and social policy. If so, we are likely to hear much more about moral injury—unfortunately, not for the right reasons.
